You’re looking at the forecast, bracing for another cold UK winter. Your central heating is running, but the bills are a worry, and some rooms never seem to get truly warm. You’ve heard about infrared heaters and wonder if they could be the solution. Are they good for our specific, damp, and often draughty winters?
The short answer is yes, but with important caveats. Infrared heaters work differently from conventional heaters, and understanding this is key to using them effectively. They can be brilliant for targeted warmth in a cold spot, but they’re not always the best choice for heating an entire, poorly insulated house. Let’s cut through the hype and get practical.
For instance, if you need a powerful, focused heat source for a frequently used spot like a home office or a chilly corner of the living room, a model like the UK 30 Infrared heater is a solid option many users find reliable for direct, instant warmth.
How Infrared Heaters Work: The Science of Radiant Warmth
To grasp why infrared heaters behave differently in the cold, you need to understand the core principle: radiant heat. Unlike fan heaters or oil-filled radiators that primarily warm the air (convection), infrared panels and quartz tube heaters emit electromagnetic waves. These waves travel until they hit a solid objectlike you, your sofa, or the wallsand transfer energy directly.
Think of it like sunshine on a frosty day. The air might be cold, but standing in a sunbeam feels warm on your skin. That’s direct transfer of energy. This method bypasses the air, which is why infrared can feel more immediately comforting. It heats objects and people first, not the airspace.
This leads to a key point about thermal efficiency. Because the heat isn’t lost to circulating air, especially in draughty spaces, less energy can be wasted. The warmth is felt almost instantly, with no wait for the entire room’s air temperature to rise.
Far Infrared Heating and Thermal Comfort
Most modern domestic infrared heaters use far infrared waves. These are perfectly safe and are the same type of warmth you feel from the sun or a traditional coal fire. This technology is central to achieving genuine thermal comfortthe feeling of being pleasantly warmrather than just raising a thermostat number.
Infrared Heaters vs. UK Winters: Strengths and Limitations
So, how does this unique heating method stack up against a typical British winter? Let’s break down the pros and cons in a cold, often damp climate.
Strengths in the Cold
- Instant, Direct Warmth: You feel the heat the moment you switch it on. No pre-heating period is needed, which is perfect for quick warmth when you enter a cold room.
- Effective in Draughts: Since it doesn’t rely on warming air, a radiant heater can be more effective in a draughty room. The warmth hits you before the cold air carries it away. This makes them a contender for the best heater type for a chilly, older bedroom with single-glazed windows.
- Silent Operation: No fans mean no noise, just quiet warmth.
- Good for High Ceilings: In rooms with high ceilings, warm air from convection heaters rises and gets trapped, wasting energy. Infrared’s direct approach avoids this pitfall.
Limitations and Considerations
- Localised Heating: This is the biggest factor. It heats what’s in its line of sight. If you move out of the beam, you’ll feel cooler. It’s excellent for a “personal warmth” zone but less so for evenly heating a large, open-plan area.
- Impact of Room Insulation: While less affected by draughts, the objects it heats (like walls) will still lose heat to a poorly insulated space. The overall effectiveness is still tied to your home’s thermal efficiency. Pairing an infrared heater with efforts like using the best ways to stop loft draughts will yield far better results.
- Do infrared heaters work in freezing temperatures? Technically, yes. The heater itself will emit infrared waves regardless of air temperature. However, in a freezing garage or outbuilding, the objects being heated are starting from a much colder state, so it may take longer for you to perceive the warmth, and you’ll need a sufficiently powerful model.
Cost Analysis: Running Costs & Efficiency in Cold Weather
This is the million-dollar question: are infrared heaters cheap to run in winter? The answer depends entirely on how you use them.
All electric heating is 100% efficient at the point of use, meaning all the electricity is converted to heat. The difference lies in how that heat is delivered and perceived. Infrared can feel more efficient because you feel the benefit immediately, potentially allowing you to use it for shorter periods.
Detailed kWh Cost Calculations
Let’s get specific. Running cost is about the heater’s power (kW) and your electricity tariff (pence per kWh).
| Heater Power | Hourly Cost (at 34p/kWh) | Scenario |
|---|---|---|
| 800W (0.8kW) | ~27p | Low-power panel for personal desk use |
| 1500W (1.5kW) | ~51p | Standard portable electric heater for a small room |
| 2000W (2.0kW) | ~68p | High-power heater for a larger or very cold space |
Based on an approximate UK standard variable tariff. Always check your actual rate.
An infrared heater used for 3 hours an evening on a 1500W setting costs about 1.53 daily. Used as targeted, supplemental heating, this can be cheaper than turning up the whole-house thermostat. Used as a primary heat source for 8+ hours a day, your heating costs will climb significantly. The key is strategic use.
Safety, Placement & Best Practices for Effective Use
Infrared heaters are generally very safe. No exposed, red-hot elements are common in modern designs, and with no fan, there’s no risk of burning dust smells. However, correct placement is non-negotiable for safety and performance.
Installation and Placement Tips
- Maintain Clearance: Follow the manufacturer’s guidance, but typically keep at least 1 metre clear of furniture, curtains, and bedding.
- Angle for Direct Impact: Position it to shine on where you’ll be sitting or working. Wall-mounted panels are great for fixed seating areas.
- Height Matters: For the best direct heat experience, mounting at head height when seated is ideal. Too high and the warmth goes over your head; too low and it’s mostly warming your legs.
- Use a Thermostat: Many models come with or can be paired with a plug-in thermostat. This prevents waste by switching the heater off once the room (or more accurately, the object in its beam) reaches a set temperature.
Infrared vs Oil Filled Radiator UK: A Quick Comparison
This is a common dilemma. Heres a snapshot for UK conditions:
- Heat-Up Time: Infrared wins. Instant vs. 15-30 minutes for an oil radiator.
- Heat Spread: Oil radiator wins for whole-room, background warmth via convection. Infrared wins for targeted, spot heating.
- Running Cost: Comparable per kWh, but usage pattern dictates final cost. Infrared can be cheaper for short bursts; an oil radiator’s residual heat might be more efficient for longer periods.
- Portability: Both are portable heaters, but oil radiators are heavier. Infrared panels are often lighter and wall-mountable.
For an all-night background heat in a bedroom, an oil-filled radiator might be better. For warming up fast in a home office for a few hours, infrared often has the edge.
Alternatives & Final Verdict: Is Infrared Right For You?
Infrared is one tool in the electric heating toolbox. Fan heaters are cheaper upfront but noisy and draught-prone. Convection heaters (like those from Dimplex) provide good ambient warmth but can be slow. Advanced bladeless models like some from Dyson offer filtered, widespread heat but at a premium price.
When an Infrared Heater is a Great Choice:
- You need fast, direct warmth for a specific person or spot.
- You have a draughty room where warming the air is inefficient.
- You want silent operation (e.g., for a bedroom or study).
- You’re looking for supplemental heating to avoid turning the central heating up.
When to Consider Another Option:
- You need to heat an entire large, open room evenly.
- You want background heat for many hours unattended (a thermostat-controlled oil radiator or electric radiator may be better).
- Your primary goal is the absolute lowest possible running cost for whole-house heating (in which case, improving insulation and using a modern gas boiler or heat pump is the real answer).

So, are infrared heaters good for cold UK winters? Absolutelyif you use them for their intended purpose. They excel at delivering immediate, comforting radiant heat right where you need it, making them a powerful ally against draughts and cold spots. They won’t single-handedly solve the problem of a poorly insulated home, but as part of a smart heating strategy, they can boost your comfort and potentially help manage your energy bills. Choose based on your specific scenario, use it strategically, and you’ll find it a very effective piece of winter kit.
